It goes more in-depth, offering advice like if someone makes a mean joke then the student should agree and say something like "if you think I'm ugly, you should see my sister," for example.

"The number one reason bullies hate their victims, is because the victims tell on them," another line reads. "Telling makes the bully want to retailiate."

Zeman Elementary School parent Ben Dinger was one of the parents who saw the flier and posted it to social media.

"My basic reaction was a bit of shock, then I wanted to find out why it was being taught." Dinger told the Sentinel. "I tried to look at the flier from a lot of directions, and when I couldn't find a good way - I got in touch with the school."

The Lincoln Public School systems has since apologized for the flier, which some people across the Web are calling the "worst bullying advice ever."

"The flyer was sent home with good intentions, unfortunately, it contained advice that did not accurately reflect LPS best practices regarding response to bullying incidents," the school system wrote on Facebook.

The apology also included a link providing information about what the school says is a more effective way to deal with bullies. Tips for parents on that site include listening to your child, keeping written accounts of each bullying incident and developing a strong school-home relationship.

But in comments on its page, LPS insists that the flier wasn't produced by anyone within the school system.

Zeman Elementary School parent Jamalee Scaggs told the Sentinel in an email that the flier was produced by a program called Bullies2Buddies. That program boasts some of the same idealogies listed in flier. Advice on its website includes "how to change your attitude" and "how to stop people from hating you."

Iggy Kalman, the founder of Bullies2Buddies, said that personnel with his program didn't create the flier, but it is based on his program's teaching and he believes someone copied his work without permission.

In response to the attention the flier has received, Kalman said he's glad it's led "to such a large controversy" and despite the criticism he stands by his teachings and the content that was put in the flier.

“The truth is these ideas are solid and they work, it’s just contrary to what the popular approach to bullying teaches. If you look at the research, the popular approach doesn’t work -- it makes things worse.”

In an article on the Bullies2Buddies website, Kalman explains why he believes the popular approach to teaching bullying doesn't work, that article is available here.

Scaggs said that she had a brief conversation with another parent about the flier on April 9, then found the flier in her fifth-grade daughter's backpack on Monday. Scaggs said she was initially "bothered" by the content in the flier but wanted some other parents' opinions.

"While some of the information is ludicrous, I do believe it would have been less objectionable had it been entitled 'How to deal with teasing' and removed bullying all together," Scaggs said in an email interview.

She says her daughter, who has been diagnosed with a mild form of autism, has never been bullied at school but that sometimes her fourth-grade son will be teased by friends.

The incident at Zeman Elementary has gained national attention, but Scaggs says she is still unclear as to how or why the fliers were sent home. She said she believes the fliers were sent out with good intentions although "it was poor judgement and extremely poor wording," she said.

Dinger agreed, saying that he appreciates the schools quick response to inform parents and educate students, but he said the information listed in the flier is "dangerous."

"My overall problem just is that what some movements like this, and the flier don't realize is what it truly is like for a kid who was bullied," Dinger wrote in an email. "Even minor bullying, which is what it seems the flier was designed to combat, is something that can escalate so quickly that all these things go out the window."

Director of Student Services at LPS told 10/11 Now that school officials are planning to meet with the fifth grade students and tell them how they believe bullying should be handled.

"What I would like to see happen is for the blame, threats, and putdowns to come to an end so the attention could be focused on teaching our kids skills to empower themselves, and to build self-worth and good judgement," Scaggs wrote.

Common Core may be the most controversial education issue you know nothing about. It's been trashed on radio talk shows and touted in speeches, and it will be the subject of three public hearings across the state this month. Yet 55 percent of parents are clueless about the nationwide...
